BACKGROUND OF THE INVENTION Field of the Invention

The invention relates to a transcatheter heart valve replacement (A61F2/2412).

Description of the Related Art

In 1952 surgeons implanted the first mechanical heart valve, a ball valve that could only be placed in the descending aorta instead of the heart itself. For this reason it did not fully correct the valve problem, only alleviate the symptoms. However it was a significant achievement because it proved that synthetic materials could be used to create heart valves.

In 1960, a new type of valve was invented and was successfully implanted. This valve is the Starr-Edwards ball valve, named after its originators. This valve was a modification of Hufnagel's original valve. The ball of the valve was slightly smaller and caged from both sides so it could be inserted into the heart itself.

The next development was tilting disc technology which was introduced in the late 1960s. These valves were a great improvement over the ball designs. The tilting dic technology allowed blood to flow in a more natural way while reducing damage to blood cells from mechanical forces. However, the struts of these valves tended to fracture from fatigue over time. As of 2003, more than 100,000 Omniscience and 300,000 Hall-Kaster/Medtronic-Hall tilting disc valves were implanted with essentially no mechanical failure.

In 1977, bi-leaflet heart valves were introduced by St. Jude. Similar to a native heart valve, blood flows directly through the center of the annulus of pyrolytic carbon valves mounted within nickel-titanium housing which makes these valves superior to other designs. However, a downside of this design is that it allows some regurgitation. A vast majority of mechanical heart valves used today have this design. As of 2003, more than 1.3 million St. Jude valves were deployed and over 500,000 Carbomedics valves with no failures to leaflets or housing. It should be noted that the human heart beats about 31 million times per year.

Development continues with compressible valves that are delivered via a catheter instead of requiring the trauma and complications of open heart surgery. This means that a cardiologist trained in endoscopy can, in theory, deploy a heart valve replacement during an outpatient procedure. However, transcatheter valves are often delivered by perforating the apex of the heart to access the ventricle, and the perforation is often used to anchor an annular valve replacement.

Additionally, a problem with stent-style replacement valves is that they often continue to have the regurgitation or leakage problems of prior generations of valves, as well as require expensive materials engineering in order to cope with the 100's of millions of cycles encountered during just a few years of normal heart function. Accordingly, there is still a need for alternative and simpler solutions to addressing valve-related heart pathologies.

Definitions

Side-Delivery or Orthogonal Delivery

In the description and claims herein, the terms “side-delivered”, “side-delivery”, “orthogonal”, “orthogonally delivered” and so forth are used to describe that the valves of the present invention are compressed and delivered at a roughly 90 degree angle compared to traditional transcatheter heart valves. Orthogonal delivery is a transverse delivery where a perimeter distal sidewall exits the delivery catheter first, followed by the central aperture, followed by the proximal sidewall.

Traditional valves have a central cylinder axis that is parallel to the length-wise axis of the delivery catheter and are deployed from the end of the delivery catheter and expanded radially outward from the central annular axis, in a manner akin to pushing a closed spring-loaded umbrella out of a sleeve to make it spring open. However, the valves of the present invention are compressed and delivered in a sideways manner. To begin with the shape of the expanded valve is that of a large diameter shortened cylinder with an extended collar or cuff. The valves are compressed, in one preferred embodiment, where the central axis of the valve is roughly perpendicular to (orthogonal to) the length-wise axis of the delivery catheter. In one preferred embodiment, the valves are compressed vertically, similar to collapsing the height of a cylinder accordion-style from taller to shorter, and the valves are also compressed by folding a front panel against a back panel. In another preferred embodiment, the valves may be compressed by rolling.

Traditional valves can only be expanded as large as what the internal diameter of the delivery catheter will allow. Efforts to increase the expanded diameter of traditional valves have run into the problems of trying to compress too much material and structure into too little space.

Mathematically, the term orthogonal refers to an intersecting angle of 90 degrees between two lines or planes. As used, herein the term “substantially orthogonal” refers to an intersecting angle ranging from 75 to 105 degrees. The intersecting angle or orthogonal angle refers to both (i) the relationship between the length-wise cylindrical axis of the delivery catheter and the long-axis of the compressed valve of the invention, where the long-axis is perpendicular to the central cylinder axis of traditional valves, and (ii) the relationship between the long-axis of the compressed or expanded valve of the invention and the axis defined by the blood flow through the prosthetic heart valve where the blood is flowing, eg. from one part of the body or chamber of the heart to another downstream part of the body or chamber of the heart, such as from an atrium to a ventricle through a native annulus.

Transcatheter

In the description and claims herein, the term “transcatheter” is used to define the process of accessing, controlling, and delivering a medical device or instrument within the lumen of a catheter that is deployed into a heart chamber, as well as an item that has been delivered or controlled by such as process. Transcatheter access is known to include via femoral artery and femoral vein, via brachial artery and vein, via carotid and jugular, via intercostal (rib) space, and via sub-xyphoid. Transcatheter can be synonymous with transluminal and is functionally related to the term “percutaneous” as it relates to delivery of heart valves.

In preferred embodiments of the invention, the transcatheter approach includes (i) advancing to the tricuspid valve or pulmonary artery of the heart through the inferior vena cava via the femoral vein, (ii) advancing to the tricuspid valve or pulmonary artery of the heart through the superior vena cava via the jugular vein, (iii) advancing to the mitral valve of the heart through a trans-atrial approach, e.g. fossa ovalis or lower, via the IVC-femoral or the SVC-jugular approach.

Annular Support Frame

In the description and claims herein, the term “annular support frame”, and also “wire frame” or “flange” or “collar” refers to a three-dimensional structural component that is seated within a native valve annulus and is used as a mounting element for a leaflet structure, a flow control component, or a flexible reciprocating sleeve or sleeve-valve.

In a preferred embodiment, the annular support frame is a self-expanding annular support frame, having a central channel and an outer perimeter wall circumscribing a central vertical axis in an expanded configuration. The perimeter wall encompasses both the collar and the lower body portions.

The perimeter wall can be further defined as having a front wall portion and a back wall portion, which are connected along a near side (to the IVC) or proximal side to a proximal fold area, and connected along a far or distal side to a distal fold area.

This front wall portion can be further defined as having a front upper collar portion and a front lower body portion, and the the back wall portion can be further defined as having a back upper collar portion and a back lower body portion.

The annular support frame has a flow control component mounted within the annular support frame and configured to permit blood flow in a first direction through an inflow end of the valve and block blood flow in a second direction, opposite the first direction, through an outflow end of the valve.

Since the frame is preferably made of superelastic metal or alloy such as Nitinol, the frame is compressible. Preferably, the frame is constructed of a plurality of compressible wire cells having a orientation and cell geometry substantially orthogonal to the central vertical axis to minimize wire cell strain when the annular support frame when configured in a vertical compressed configuration, a rolled compressed configuration, or a folded compressed configuration.

Annular Support Frame Structure

The annular support frame can be a ring, or cylindrical or conical tube, made from a durable, biocompatible structural material such as Nitinol or similar alloy, wherein the annular support frame is formed by manufacturing the structural material as a braided wire frame, a laser-cut wire frame, or a wire loop. The annular support frame is about 5-60 mm in height, has an outer diameter dimension, R, of 30-80 mm, and an inner diameter dimension of 31-79 mm, accounting for the thickness of the wire material itself. As stated, the annular support frame can have a side-profile of a ring shape, cylinder shape, conical tube shape, but may also have a side profile of a flat-cone shape, an inverted flat-cone shape (narrower at top, wider at bottom), a concave cylinder (walls bent in), a convex cylinder (walls bulging out), an angular hourglass, a curved, graduated hourglass, a ring or cylinder having a flared top, flared bottom, or both.

In one preferred embodiment, the annular support frame used in the prosthetic heart valve deployed in the tricuspid annulus may have a complex shape determined by the anatomical structures where the valve is being mounted. For example, in the tricuspid annulus, the circumference of the tricuspid valve may be a rounded ellipse, the septal wall is known to be substantially vertical, and the tricuspid is known to enlarge in disease states along the anterior-posterior line. Accordingly, a prosthetic heart valve may start in a roughly tubular configuration, and be heat-shaped to provide an upper atrial cuff or flange for atrial sealing and a lower trans-annular tubular or cylindrical section having an hourglass cross-section for about 60-80% of the circumference to conform to the native annulus along the posterior and anterior annular segments while remaining substantially vertically flat along 20-40% of the annular circumference to conform to the septal annular segment.

In a preferred embodiment, the horizontal x-axis of the valve is orthogonal to (90 degrees), or substantially orthogonal to (75-105 degrees), or substantially oblique to (45-135 degrees) to the central vertical y-axis when in an expanded configuration.

In a preferred embodiment, the horizontal x-axis of the compressed configuration of the valve is substantially parallel to a length-wise cylindrical axis of the delivery catheter.

In another preferred embodiment, the valve has a compressed height (y-axis) and width (z-axis) of 6-15 mm, preferably 8-12 mm, and more preferably 9-10 mm, and an expanded deployed height of about 5-60 mm, preferably about 5-30 mm, and more preferably about 5-20 mm or even 8-12 mm or 8-10 mm. It is contemplated in preferred embodiments that the length of the valve, x-axis, does not require compression since it can extend along the length of the central cylindrical axis of the delivery catheter.

In a preferred embodiment, the valve has an expanded diameter length and width of 25-80 mm, preferably 40-80 mm, and in certain embodiments length and/or width may vary and include lengths of 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, and 80 mm, in combination with widths that are the same or different as the length.

In certain preferred embodiments, the valve is centric, or radially symmetrical. In other preferred embodiments, the valve is eccentric, or radially (y-axis) asymmetrical. In some eccentric embodiments, the outer frame may have a D-shape (viewed from the top) so the flat portion can be matched to the mitral annulus near the anterior leaflet.

In certain preferred embodiments, the inner frame holding the leaflet tissue is 25-29 mm in diameter, the outer frame is 50-70 mm in diameter, and the collar structure extends beyond the top edge of the outer frame by 10-30 mm to provide a seal on the atrial floor against perivalvular leaks (PVLs).

The atrial collar is shaped to conform to the native deployment location. In a mitral replacement, the atrial collar will be configured with varying portions to conform to the native valve. In one preferred embodiment, the collar will have a distal and proximal upper collar portion. The distal collar portion can be larger than the proximal upper collar portion to account for annular or subannular geometries.

Annular Support Frame Covering

The annular support frame is optionally internally or externally covered, partially or completely, with a biocompatible material such as pericardium. The annular support frame may also be optionally externally covered, partially or completely, with a second biocompatible material such as polyester or Dacron (R).

Annular Support Frame Purpose

The annular support frame has a central axial lumen where a prosthetic heart valve or flow-control structure, such as a reciprocating compressible sleeve, is mounted across the diameter of the lumen. The annular support frame is also tensioned against the inner aspect of the native annulus and provides structural patency to a weakened annular ring.

Annular Support Frame Optional Collars

The annular support frame may optionally have a separate atrial collar attached to the upper (atrial) edge of the frame, for deploying on the atrial floor, that is used to direct blood from the atrium into the sleeve and to seal against blood leakage around the annular support frame. The annular support frame may also optionally have a separate ventricular collar attached to the lower (ventricular) edge of the frame, for deploying in the ventricle immediately below the native annulus that is used to prevent regurgitant leakage during systole, to prevent dislodging of the device during systole, to sandwich or compress the native annulus or adjacent tissue against the atrial collar, and optionally to attach to and support the sleeve/conduit.

Annular Support Frame Delivery

The annular support frame may be compressed for transcatheter delivery and may be expandable as a self-expandable shape-memory element or using a transcatheter expansion balloon. Some embodiments may have both an atrial collar and a ventricular collar, whereas other embodiments within the scope of the invention include prosthetic heart valves having either a single atrial collar, a single ventricular collar, or having no additional collar structure.

Frame Material

Preferably, the frame is made from a superelastic metal component, such as laser-cut Nitinol tube, or flat sheet or other similarly functioning material such as braided wire. The material may be used for the frame/stent, for the collar, and/or for anchors. It is contemplated as within the scope of the invention to use other shape memory alloys, as well as polymer composites including composites containing carbon nanotubes, carbon fibers, metal fibers, glass fibers, and polymer fibers. It is contemplated that the frame may be constructed as a braid, wire, or laser cut frame. Laser cut frames are preferably made from Nitinol, but also without limitation made from stainless steel, cobalt chromium, titanium, and other functionally equivalent metals and alloys.

One key aspect of the frame design is that it be compressible and when released have the stated property that it returns to its original (uncompressed) shape. This requirement limits the potential material selections to metals and plastics that have shape memory properties. With regards to metals, Nitinol has been found to be especially useful since it can be processed to be austenitic, martensitic or super elastic. Martensitic and super elastic alloys can be processed to demonstrate the required mechanical behavior.

Laser Cut

One possible construction of the wire frame envisions the laser cutting of a thin, isodiametric Nitinol tube. The laser cuts form regular cutouts in the thin Nitinol tube. In one preferred embodiment, the Nitinol tube expands to form a three-dimensional structure formed from diamond-shaped cells. The structure may also have additional functional elements, e.g. loops, anchors, etc. for attaching accessory components such as biocompatible covers, tissue anchors, releasable deployment and retrieval control guides, knobs, attachments, rigging, and so forth.

Secondarily the tube is thermo-mechanically processed using industry standard Nitinol shape forming methods. The treatment of the wire frame in this manner will form a device that has shape memory properties and will readily revert to the memory shape once deployed.

Braided Wire

Another possible construction of the wire frame envisions utilizing simple braiding techniques using a Nitinol wire and a simple braiding fixture. The wire is wound on the braiding fixture in a pattern until an isodiametric tube is formed. Secondarily, the braided wire frame is placed on a shaping fixture and processed using industry standard Nitinol shape forming methods.

Flow Control Component

In the description and claims herein, the term “flow control component” refers in a non-limiting sense to a leaflet structure having 2-, 3-, 4-leaflets of flexible biocompatible material such a treated or untreated pericardium that is sewn or joined to a annular support frame, to function as a prosthetic heart valve. Such a valve can be a heart valve, such as a tricuspid, mitral, aortic, or pulmonary, that is open to blood flowing during diastole from atrium to ventricle, and that closes from systolic ventricular pressure applied to the outer surface.

Repeated opening and closing in sequence can be described as “reciprocating”.

Tissue Anchor

In the description and claims herein, the term “tissue anchor” or “plication tissue anchor” or “secondary tissue anchor”, or “dart” or “pin” refers to a fastening device that connects the upper atrial frame to the the native annular tissue, usually at or near the periphery of the collar. The anchor may be positioned to avoid piercing tissue and just rely on the compressive force of the two plate-like collars on the captured tissue, or the anchor, itself or with an integrated securement wire, may pierce through native tissue to provide anchoring, or a combination of both. The anchor may have a specialized securement mechanism, such as a pointed tip with a groove and flanged shoulder that is inserted or popped into a mated aperture or an array of mated apertures that allow the anchor to attach, but prevent detachment when the aperture periphery locks into the groove near the flanged shoulder. The securement wire may be attached or anchored to the collar opposite the pin by any attachment or anchoring mechanisms, including a knot, a suture, a wire crimp, a wire lock having a cam mechanism, or combinations.

Support Post

The term “support post” refers to a rigid or semi-rigid length of material such as Nitinol or PEEK, that may be mounted on a spoked frame and that runs axially, or down the center of, or within a sewn seam of -, the flexible sleeve. The sleeve may be unattached to the support post, or the sleeve may be directly or indirectly attached to the support post.

In the description that follows, the term “body channel” is used to define a blood conduit or vessel within the body. Of course, the particular application of the prosthetic heart valve determines the body channel at issue. An aortic valve replacement, for example, would be implanted in, or adjacent to, the aortic annulus. Likewise, a tricuspid or mitral valve replacement will be implanted at the tricuspid or mitral annulus. Certain features of the present invention are particularly advantageous for one implantation site or the other. However, unless the combination is structurally impossible, or excluded by claim language, any of the heart valve embodiments described herein could be implanted in any body channel.

The term “lumen” refers to the inside of the cylinder tube. The term “bore” refers to the inner diameter.

As a point of further definition, the term “expandable” is used herein to refer to a component of the heart valve capable of expanding from a first, delivery diameter to a second, implantation diameter. An expandable structure, therefore, does not mean one that might undergo slight expansion from a rise in temperature, or other such incidental cause. Conversely, “non-expandable” should not be interpreted to mean completely rigid or a dimensionally stable, as some slight expansion of conventional “non-expandable” heart valves, for example, may be observed.

Prosthetic Heart Valve

The term prosthesis or prosthetic encompasses both complete replacement of an anatomical part, e.g. a new mechanical valve replaces a native valve, as well as medical devices that take the place of and/or assist, repair, or improve existing anatomical parts, e.g. native valve is left in place. For mounting within a passive assist cage, the invention contemplates a wide variety of (bio)prosthetic artificial heart valves. Contemplated as within the scope of the invention are ball valves (e.g. Starr-Edwards), bileaflet valves (St. Jude), tilting disc valves (e.g. Bjork-Shiley), stented pericardium heart-valve prosthesis' (bovine, porcine, ovine) (Edwards line of bioprostheses, St. Jude prosthetic heart valves), as well as homograft and autograft valves. For bioprosthetic pericardial valves, it is contemplated to use bioprosthetic aortic valves, bioprosthetic mitral valves, bioprosthetic tricuspid valves, and bioprosthetic pulmonary valves.

Tethers

The tethers are made from surgical-grade materials such as biocompatible polymer suture material. Non-limiting examples of such material include ultra high-molecular weight polyethylene (UHMWPE), 2-0 exPFTE(polytetrafluoroethylene) or 2-0 polypropylene. In one embodiment the tethers are inelastic. It is also contemplated that one or more of the tethers may optionally be elastic to provide an even further degree of compliance of the valve during the cardiac cycle.

Tines-Anchors-Tines/Barbs

The device can be seated within the valvular annulus through the use of tines or barbs. These may be used in conjunction with, or in place of one or more tethers. The tines or barbs are located to provide attachment to adjacent tissue. Tines are forced into the annular tissue by mechanical means such as using a balloon catheter. In one non-limiting embodiment, the tines may optionally be semi-circular hooks that upon expansion of the wire frame body, pierce, rotate into, and hold annular tissue securely. Anchors are deployed by over-wire delivery of an anchor or anchors through a delivery catheter. The catheter may have multiple axial lumens for delivery of a variety of anchoring tools, including anchor setting tools, force application tools, hooks, snaring tools, cutting tools, radio-frequency and radiological visualization tools and markers, and suture/thread manipulation tools. Once the anchor(s) are attached to the moderator band, tensioning tools may be used to adjust the length of tethers that connect to an implanted valve to adjust and secure the implant as necessary for proper functioning. It is also contemplated that anchors may be spring-loaded and may have tether-attachment or tether-capture mechanisms built into the tethering face of the anchor(s). Anchors may also have in-growth material, such as polyester fibers, to promote in-growth of the anchors into the myocardium.

In one embodiment, where a prosthetic heart valve may or may not include a ventricular collar, the anchor or dart is not attached to a lower ventricular collar, but is attached directly into annular tissue or other tissue useful for anchoring.

Tube and/or Cover Material-Biological Tissue

The tissue used herein is a biological tissue that is a chemically stabilized pericardial tissue of an animal, such as a cow (bovine pericardium) or sheep (ovine pericardium) or pig (porcine pericardium) or horse (equine pericardium). Preferably, the tissue is bovine pericardial tissue. Examples of suitable tissue include that used in the products Duraguard®, Peri-Guard®, and Vascu-Guard®, all products currently used in surgical procedures, and which are marketed as being harvested generally from cattle less than 30 months old. Other patents and publications disclose the surgical use of harvested, biocompatible animal thin tissues suitable herein as biocompatible “jackets” or sleeves for implantable stents, including for example, U.S. Pat. No. 5,554,185 to Block, U.S. Pat. No. 7,108,717 to Design & Performance-Cyprus Limited disclosing a covered stent assembly, U.S. Pat. No. 6,440,164 to Scimed Life Systems, Inc. disclosing a bioprosthetic heart valve for implantation, and U.S. Pat. No. 5,336,616 to LifeCell Corporation discloses acellular collagen-based tissue matrix for transplantation.

Polymers

In one preferred embodiment, the conduit may optionally be made from a synthetic material such a polyurethane or polytetrafluoroethylene.

Where a thin, durable synthetic material is contemplated, e.g. for a covering, synthetic polymer materials such expanded polytetrafluoroethylene or polyester may optionally be used. Other suitable materials may optionally include thermoplastic polycarbonate urethane, polyether urethane, segmented polyether urethane, silicone polyether urethane, silicone-polycarbonate urethane, and ultra-high molecular weight polyethylene. Additional biocompatible polymers may optionally include polyolefins, elastomers, polyethylene-glycols, polyethersulphones , polysulphones, polyvinylpyrrolidones, polyvinylchlorides, other fluoropolymers, silicone polyesters, siloxane polymers and/or oligomers, and/or polylactones, and block co-polymers using the same.

Polyamides (PA)

PA is an early engineering thermoplastic invented that consists of a “super polyester” fiber with molecular weight greater than 10,000. It is commonly called Nylon. Application of polyamides includes transparent tubing's for cardiovascular applications, hemodialysis membranes, and also production of percutaneous transluminal coronary angioplasty (PTCA) catheters.

Polyolefin

Polyolefins include polyethylene and polypropylene are the two important polymers of polyolefins and have better biocompatibility and chemical resistance. In cardiovascular uses, both low-density polyethylene and high-density polyethylene are utilized in making tubing and housings. Polypropylene is used for making heart valve structures .

Polyesters

Polyesters includes polyethylene-terephthalate (PET), using the name Dacron. It is typically used as knitted or woven fabric for vascular grafts. Woven PET has smaller pores which reduces blood leakage and better efficiency as vascular grafts compared with the knitted one. PET grafts are also available with a protein coating (collagen or albumin) for reducing blood loss and better biocompatibility [39]. PET vascular grafts with endothelial cells have been searched as a means for improving patency rates. Moreover, polyesters are widely preferred material for the manufacturing of bioabsorbable stents. Poly-L-lactic acids (PLLA), polyglycolic acid (PGA), and poly(D, L-lactide/glycolide) copolymer (PDLA) are some of the commonly used bioabsorbable polymers.

Polytetrafluoroethylene

Polytetrafluoroethylene (PTFE) is synthetic fluorocarbon polymer with the common commercial name of Teflon by Dupont Co. Common applications of PTFE in cardiovascular engineering include vascular grafts and heart valves. PTFE sutures are used in the repair of mitral valve for myxomatous disease and also in surgery for prolapse of the anterior or posterior leaflets of mitral valves. PTFE is particularly used in implantable prosthetic heart valve rings. It has been successfully used as vascular grafts when the devices are implanted in high-flow, large-diameter arteries such as the aorta. Problem occurs when it is implanted below aortic bifurcations and another form of PTFE called elongated-PTFE (e-PTFE) was explored. Expanded PTFE is formed by compression of PTFE in the presence of career medium and finally extruding the mixture. Extrudate formed by this process is then heated to near its glass transition temperature and stretched to obtain microscopically porous PTFE known as e-PTFE. This form of PTFE was indicated for use in smaller arteries with lower flow rates promoting low thrombogenicity, lower rates of restenosis and hemostasis, less calcification, and biochemically inert properties.

Polyurethanes

Polyurethane has good physiochemical and mechanical properties and is highly biocompatible which allows unrestricted usage in blood contacting devices. It has high shear strength, elasticity, and transparency. Moreover, the surface of polyurethane has good resistance for microbes and the thrombosis formation by PU is almost similar to the versatile cardiovascular biomaterial like PTFE. Conventionally, segmented polyurethanes (SPUs) have been used for various cardiovascular applications such as valve structures, pacemaker leads and ventricular assisting device.

Covered Wire frame Materials

Drug-eluting wire frames are contemplated for use herein. DES basically consist of three parts: wire frame platform, coating, and drug. Some of the examples for polymer free DES are Amazon Pax (MINVASYS) using Amazonia CroCo (L605) cobalt chromium (Co—Cr) wire frame with Paclitaxel as an antiproliferative agent and abluminal coating have been utilized as the carrier of the drug. BioFreedom (Biosensors Inc.) using stainless steel as base with modified abluminal coating as carrier surface for the antiproliferative drug Biolimus A9. Optima (CID S.r.I.) using 316 L stainless steel wire frame as base for the drug Tacrolimus and utilizing integrated turbostratic carbofilm as the drug carrier. VESTA sync (MIV Therapeutics) using GenX stainless steel (316 L) as base utilizing microporous hydroxyapatite coating as carrier for the drug Sirolimus. YUKON choice (Translumina) used 316 L stainless steel as base for the drugs Sirolimus in combination with Probucol.

Biosorbable polymers may also be used herein as a carrier matrix for drugs. Cypher, Taxus, and Endeavour are the three basic type of bioabsorbable DES. Cypher (J&J, Cordis) uses a 316 L stainless steel coated with polyethylene vinyl acetate (PEVA) and poly-butyl methacrylate (PBMA) for carrying the drug Sirolimus. Taxus (Boston Scientific) utilizes 316 L stainless steel wire frames coated with translute Styrene Isoprene Butadiene (SIBS) copolymer for carrying Paclitaxel which elutes over a period of about 90 days. Endeavour (Medtronic) uses a cobalt chrome driver wire frame for carrying zotarolimus with phosphorylcholine as drug carrier. BioMatrix employing S-Wire frame (316 L) stainless steel as base with polylactic acid surface for carrying the antiproliferative drug Biolimus. ELIXIR-DES program (Elixir Medical Corp) consisting both polyester and polylactide coated wire frames for carrying the drug novolimus with cobalt-chromium (Co—Cr) as base. JACTAX (Boston Scientific Corp.) utilized D-lactic polylactic acid (DLPLA) coated (316 L) stainless steel wire frames for carrying Paclitaxel. NEVO (Cordis Corporation, Johnson & Johnson) used cobalt chromium (Co—Cr) wire frame coated with polylactic-co-glycolic acid (PLGA) for carrying the drug Sirolimus.

Examples of preferred embodiments of the reciprocating pressure conduit valve include the following details and features.

EXAMPLE

The transcatheter prosthetic heart valve may be percutaneously delivered using a transcatheter process via the femoral through the IVC, carotid, sub-xyphoid, intercostal access across the chest wall, and trans-septal to the mitral annulus through the fossa ovalis.

The device is delivered via catheter to the right or left atrium and is expanded from a compressed shape that fits with the internal diameter of the catheter lumen. The compressed valve is loaded external to the patient into the delivery catheter, and is then pushed out of the catheter when the capsule arrives to the atrium. The cardiac treatment technician visualizes this delivery using available imaging techniques such as fluoroscopy or ultrasound.

In a preferred embodiment the valve self-expands upon release from the catheter since it is constructed in part from shape-memory material, such as Nitinol®, a nickel-titanium alloy, or a cobalt-chromium alloy, alloys used in biomedical implants.

In another embodiment, the valve may be constructed of materials that requires balloon-expansion after the capsule has been ejected from the catheter into the atrium.

The atrial collar/frame and the flow control component are expanded to their functional diameter, as they are deployed into the native annulus, providing a radial tensioning force to secure the valve. Once the frame is deployed about the tricuspid annulus, fasteners secure the device about the native annulus. Additional fastening of the device to native structures may be performed, and the deployment is complete. Further adjustments using hemodynamic imaging techniques are contemplated as within the scope of the invention in order to ensure the device is secure, is located and oriented as planned, and is functioning as a substitute or successor to the native tricuspid valve.

(iii) flattening the annular support frame into two parallel panels that are substantially parallel to the long-axis, and then rolling the flattened annular support frame into a compressed configuration; and

(iv) flattening the annular support frame along a vertical axis to reduce a vertical dimension of the valve from top to bottom.
